Abstract (en)

[origin: WO0147302A1] The object of the invention is a method for changing the frequency band used by a mobile station in a mobile station system. The invention is based on the idea that instead of using a fixed threshold value to change the frequency band, it is replaced with a variable threshold value in connection of a failed attempt to change the frequency band. The variable threshold value is based on the signal levels measured on both frequency bands and used to obtain the new threshold value. A fresh attempt to change the frequency band is made applying the new threshold value.
